How can you tell which direction a glacier moved?
You can determine the direction a glacier moved by examining the features it left behind. Striations, which are scratches on rocks caused by the movement of the glacier, point in the direction of flow. Additionally, the shape of landforms such as moraines and drumlins can indicate the glacier's movement direction, with moraines forming at the glacier's edges and drumlins aligned in the direction of flow. Lastly, the orientation of glacial deposits can also provide clues about the glacier's path.
A boulder moved by a glacier is called a what?
A boulder moved by a glacier is called a "glacial erratic." These large rocks are transported by the glacier as it advances and subsequently deposited in a different location when the glacier retreats. Glacial erratics can be composed of various types of rock and are often found in areas where the local geology is different from the rock type of the erratic itself.
How can you tell how far a rock or boulder has been moved by a glacier?
To determine how far a rock or boulder has been moved by a glacier, scientists often examine the rock's shape and striations, which can indicate the direction of glacial flow. Additionally, comparing the rock's composition to the surrounding geology helps identify its origin. By mapping the distribution of similar rocks and using tools like GPS or surveying, researchers can estimate the distance the glacier has transported the boulder. Analyzing sediment layers and glacial deposits also provides insights into the glacier's movement history.
How can you tell if a glacier had once moved across a region?
Signs that indicate a glacier once moved across a region include: striations on rocks, moraines (ridges of debris), U-shaped valleys, glacial polish on bedrock, and erratic boulders (rocks that are different from the surrounding bedrock).
What is a rock that is moved by a glacier?
A rock that is moved by a glacier is called a glacial erratic. These rocks can vary in size and type, and are often deposited in areas far from their original source by the movement of the glacier. Glacial erratics are important indicators of past glacial activity and can provide valuable information about the history of a region.

What does a glacier do to the surface of the earth as it recedes?
the glacier deposits various rocks and sediment it displaced as it moved forward
Did Antarctica move north as a glacier in the ice age?
Antarctica is a continent, not a glacier, and has only ever moved south.

How do you tell someone you love him when you have moved on?
how can you tell if someone has moved on
Which is a sign that a valley glacier has moved through an area?
A sign that a valley glacier has moved through an area is the presence of U-shaped valleys, which have been carved by the glacier's movement. Additionally, features like striations on bedrock, polished surfaces, and glacial moraines—accumulations of debris—often indicate past glacial activity. These features reflect the powerful erosive forces of the glacier as it advanced and retreated.
What is a morraine made of?
A moraine is a accumulation of rock debris, gravel, sand, and silt that is moved and deposited by a glacier. It is composed of a mixture of materials that the glacier has eroded and transported as it moves.
How do you tell if a valley glacier is advancing or retreating?
Valley glaciers are typically advancing when their terminus is pushing forward, causing the glacier to grow in size. Conversely, they are retreating if the terminus is melting or receding, leading to a decrease in glacier size. Monitoring changes in the glacier front position over time can help determine if it is advancing or retreating.
What does materials bulldozed at the front of the glacier form?
When materials are bulldozed at the front of a glacier, they form a ridge-like feature called a moraine. Moraines are composed of a mixture of rock, sediment, and debris that were pushed and carried by the glacier as it moved forward.
